Chocolate and cocoa are made from the beans or seed of several small trees, natives of tropical America, of .which T heohroma cacao L. is by far the most important. .-2 first stages in the manufacture of both chocolate and cocoa'are the same. After removmg stones, chips, and other impurities the beans are roasted, thus developing a desirable flavor and facilitating theprocesses of sepurat ion from the shells and grinding. The beans are then crushed by machinery and separated from the shells. In some factories the germs (rootlets) are also removed. The broken cotyledons, free from shells and known cocoa-rubs, are next ground the cluuzolate-mill. The heat of grinding its the fat, which makes up about half the ght of the nibs, and the ground product runs out of the mill as a thin paste. This paste after cooling in molds is the unsweetened chocolate of commerce. Sweet chocolate is prepared by mixing pulverized sugar and vanilla or other flavor with the Warm chocolate paste before molding.

Cocoa is prepared by removing a portion of the fat from the warm mass by pressure and reducing the residue to a powder, with or Without addition of vanilla flavor. Dut chprocess cocoa 1S cocoa treated with an al- Specificatio'n of Letters Patent.

kali, usually soda or ammonia, with a View of reventing the collecting of fat on the surface of a beverage prepared therefrom. This is sometimes'called soluble cocoa. Cacaobutter is the expressed'fat obtained as a byproduct in the manufacture of cocoa.

The present invention is founded upon the discovery that the more nearly a fat or. oil sup 'lied to. the human system ap roximates in t e proportions of the olein, pa mitin, and stearin in its fat content the proportions of the like'proximate constituents in the human fat the more readily is the same absorbed, di-

gested, and assimilated. Of any fat eaten ,by man only the proportion of olein, palmitin, and stearin foun in that of the human fat will be assimilated, and any excess of such elements is not only a Waste, but entails upon the system the burden of expelling the same, whereby the digestion of the remainder of the food preparation is impeded.

The fat content of cocoa, chocolate, and cacao-butter is not analogous in respect of the proportions of its olein, palmit-in, and

' 'stearin to the like proximate principles or elements of hunian fat, and in the methods hitherto practiced in the production of said gous to that of human fat.

The object of my invention is obtained by modifying the composition of the oil or fat of cocoa, chocolate, confectionery, cacaobutter, and other cocoa products as regards the proportions of its olein, palmitin, and stea'rin content,-so as to make the proportions of the same in the finished edible product approximate the proportions of'the like proximate constituents found in human fat.

The human fat in some cases has been found to comprise in adults 86.21 per cent. olein, 7.85 per cent. palmitin, 1.93 per cent. stearin, (or proportions 898328161201) end in a child 65.04 per cent. olein, 27.81 per cent. palmitin, 3.15 per cent. stearin, (or propor- Such percentages and proportions may be found to vary for different ages and conditions of man. The

scope of my invention covers any such varialIO cocoas, vary in the percentages of the fat content. In the bean or nib it varies from 36.8 to 50.9 per cent. I take the average of fat in the cocoa-nib used by me at fifty per cent, in average commercial cocoa or chocolate at twenty-five er cent., and the composition of .the average at'of cacao-beans I find includes or comprises about thirty per cent. olein and seventeen per cent. palmltin 'and forty per cent. stearin; In manufacturing in quantity I not only ascertain approximately the percentage of total fat in the cacao-bean, but

also the approximate composition as regards olei'n, palmitin, and stea'rin of such fats.

In my invention there is incorporated with the cocoa or chocolate mass an oil ingredient oncompoundoilhaving a known content of olein, palmitin, and stearin which when added to the duly-ascertained oil in the cocoa or chocolate shall constitute the same approximately of the predetermined oil formula aforesaid.

Method A: Inthe practice of my process I can incorporate or mix the said ingredient or compound oil with the-hot-thin cocoa paste or mass as it runs from the ordinary cocoa or chocolate milllon first grinding the cocoa nibs or-seeds and thereafter express or otherwise mmove from the Whole mixture any desired amount of the new product oil which forms my new cacao butter or fat and in amount requisite to reduce the amount of oil or fat-re maining in the cocoa or chocolate product either'to the amount as now commonly pr ferred or any other desired amount. The aforesaid expressed oil, as also the oil in the canoe, is of the predetermined oil formula.

Method B: I prefer, however, this method, wherein I first express from said hot cocoa paste any amount, preferably about seventyfive per cent. to ninety per cent, of its native oil, as now practiced in the manufacture of commercial cocoa, and thereupon add and incorporate in the remaining paste my aforesaid com ound in amount duly calculated to give in t e roduct the com osition aforesaid, and, if esired', I may maize a second expression of excess fat from such newly-mixed paste to attain a dry remaining product which can be pulverized, if desired. The cacao-butter first ex ressed in this form of the process is utilized y adding or incorporating with it a due amount of my compound oil to constitute it of the predetermined formula,

thus making it a form of my improved cacaobutter. The second pressing aforesaid is of the said formula.

Though I prefer to incorporate my compound oil as aforesaid, especially when I manufacture the cocoa or chocolate from the nibs or'seed, yet I do not restrict myself thereto, but can and do also treat and modify the commercial ooooas and chocolates of any manufacture by incorporating and mixing therewith while the same is in a iinelypulverized state my compound oil in duly-calculated amount and expressing excess oils from the resulting mass.

As examples applicable to either Method A or Method B and of my methods of modifying the fat ofcocoa to constitute the fat therein as regards its oicin, palmitin, and

stearin content of approximately the propor' I mix a compound oil comprising- Olein No. 1. comprising. 68.36 4.02 1.05 4% Oliye-oil palmitin. comprising. .34- 4. 0

98 5 TotaLcomprising 68.68 29.05 3.28

being approximately the proportions of olein, palmitin, and stea-rin as found in child fat. In this example if I follow Method A, I add 19.6 units of my compound oil for each unit of native oil in the cacao. This total amount being excessive for consum tion from the standpoint of a weli-balance food, I express from the resulting cocoa any desired amount. Thus if the native cacao contained fifty per cent. fat then for each one-pound cocoa,

when the same is first expressed from theseed and while in a warm molten mass, I mix and incorporate by well-known moans 19.6 X pound. 9.6 pounds of my said compound oil, preferably by thoroughly mixing in an oniulslonizing-nmchine or in a chocolate-mixer or mlangeur. I then filter or express therefrom in any suitable filter or press, preferably a centrifugal filter, the excess of oils until I have reduced the amount of oil remaining in the cocoa mass to any desired percentage. I prefer a remainder of about ten per cent. to attain adry or pulverizable product, though I also in some forms permit about twenty-five per cent. to remain, thus constituting the amount in ordinary commercial cocoa; but modified, as aforesaid, and in other forms made by me 1 permit about fifty per cent. of oil to remain in the cocoa mass Where such cocoa is to be used for making chocolate and Where the public may prefer such; but in such case also the remaining cacao fat has been modilied, as aforesaid. The said fifty per cent. of fat in cocoa is usually reduced to about twentyfive per cent. of the total chocolate, as the latter has a material amount of sugar in its composition, usually fifty per cent. of sugar.

in my preferred Method B, i first express from the cocoa paste the maximum amount of oil possible. I prefer a hydraulic press to press the paste kept at a temperature of about 140 Fahrenheit and to remove from each one pound of cocoa paste containing originally fifty per cent. of fat sufficient fat so that one pound of cocoa paste remaining shall contain ten per cent, or even less, of far. To modify the latter, to each one ppund of such paste containing one-tenth of a pound of carao-oil I add (or with it I- mix) 19.6% =LQ6 pounds of my said compound oil, (Example 3,) or approximately two pounds. I now have a cocoa paste of three pounds weight, whereof two pounds,or approximately so, (or about sixty-six and two-thirds per cent.) is my improved oil of the predetermined child-oil formula. For use in making chocolate I express therefrom one-sixth of its Weight of 011, thus reducing the same to fifty per cent. of oil. For use as cocoa 1 prefor to express sullicient oil until its oil con tent is reduced to twenty-five per cent. of the total weight. The oil expressed as ,aforesaid is of the predetermined oil forniula. The aforesaid com ound oils are prepared substantially as tesc-ribed in my patent application, Serial No. 198,364, filed Marc-h 14, 190 i, excepting substituting'the above compound oil formulas, respectiitely. The olive-oil palmitin is obtained from i a.- tire olive-oil by subsidence and solidifies tion of the solid fat in the olive-oil at a low temperature, preferabiy of about to l ahrenhe it, and thereafter preferably fil tering the liquid fats therefrom. The cot ton-seed palmitin is likewise obtained from the cotton-seed stearindeposited by cold from refined winter-strained cotton-seed oil.

The aforesaid olein No. 1 is an oil of lardandwe-s pressed from choicest edible lard eergs ee at a temperature of 45 Fahrenheit at a pressure of about one hundred and sixtypounds to the square inch. I do not restrict myself to the said native oils of fats tomake my compound oil, nor to the said temperatures or methods of obtaining said fractions fats and any welldmown methods, especially of native oils. 1. can use any edible oils or those indicated in aforesaid patent application, Serial No. 198,364.

in the manufacture of cocoa or chocolate confectionery 1 preferably attain my invention by using my improved cocoa or chocolate prepared as by the aforesaid methods, and where butter or other fatis ordinarily called for by the recipe for making such confectionery I preferably substitute a like amount of the new product fat or improved 'cocoa-fat obtained, as aforesaid. 'lhus, Example i, an accepted recipe for sweet chocolate, is sugar, five pounds; glucose, one and one-fourth pounds; fresh butter, one half pound; pure cocoa unsweetened, one pound; essence of Vanilla, one-fourth of an ounce. in my method of manufacture Ii substitute for said cocoa my improved cocoa prepared as aforesaid, and I substitute for said one-half pound of butter a like amount of my cocoa-butter or fat expressed as in Method A or prepared from the fat expressed as in Method B.

in the manufacture of chocolate or cocoa confectionery in my method I prefer to use in place of-part of the sugar a quantity of honey, the amount being regulated by the. degree of sweetness to be attained, whereby the fats more readily emulsify with water in the stomach and duodenum at and below the body tem erature, thereby facilitating the digestion o the whole.

By cocoa products I include all forms of cocoa and chocolate, flavored or unfla- I vored, and cocoa or chocolate cakes, confections, candies, and drinlis, and what is called soluble chocolate used in making hot or cold soda-water drinks, and a preparation of cocoa-rubs andof cocoa with other nutritious substances with or without ilavorssuch as vanilla or cinnamon and sweeteningand cocoa butter, broma, &c. In other words, it is to be understood that the term cocoa products? or' cacao products applies to the various products of the beans or seeds from which chocolate and cocoa are produced. use the term fa-ts" herein to include oils; and vice versa. I I apply an analgous method of preparing foodstuffs.- to increase the digestibility, absorbability, and .assimilability to that herein specifically described for cacao beans to other foodstuffs comprising invisible oils, more esp cially Where the iatter comprise e: rcess of so. id fats over that called for bythe aforesaid adult or child oil formulas. This is notably the case in the ground pen or peanuts,

' remainder as which comprise about forty per cent; of fat and whereof over seven per cent. is stearin. In all such foodstuffs prefer first to remove the excess of stearin over that required by the oil formula by expressing or otherwise removing a material amount of the oil from the' foodstufi and then modify the oil in the er the method described for cacao aforesai In a'prior application filed by me January 15, 1903, Serial No. 139,201, I have claimed sundry improvements in food preparations under or upon which this is a further improvement in-and of a particular species, and I do not claim the former herein.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

1. The process of treating cacao materials to produce an improved cacao product,which comprises the step of producing a paste or mass of said materials and adding to the fat constituent thereof a fat which gives said constituent a redetermined content of .olein, palmitm, ant stearm analogous to that in which said proximate principles are found in human fat. i 2. The process of treating cacao materials to produce an improved cacao product, which comprises the steps of producing a paste or mass of said materials, adding to the fat constituent thereof a fat which gives said constituent a predetermined content of olein,

palmitin and stearin analogous to that inwhichsaid proximate princifples are foundin human fat, and expressmg om said mass a portion-of said fat.

3. The process herein described of treating cacao materials to produce an improved cacao product, consisting of the following steps:

first, reducing the materials to a paste; secmitin and stearin analo ous to that in which said proximate fat, y

5, As a new art cle of manufacture, a'cacao princip les' occur in human product in adry condition, having a fat'co'm' these proximate princi-MM tent comprising olein, palmitin and s'tearin in approximately the proportions in which these proximate principles occur in human fat.

I 6.. As a new article of manufacture,a cacao. product having a fat content comprisin olein, palmitin and stearin in approximately the proportions inwhichthese proximate princiles occur in human fat, the said'preparation heing in a dry and pulverized condition.

In testimony whereof I aflix my signature in presence of two witnesses.
